Problem 1 if it keeps happening try a static regen if it still occurs after that then you need a new vapourizer but first check the sensors wiring is ok going into the exhaust just beneath the front seats.

Problem 2 check the MAF wiring and if ok try to clean it.

Problem 3 check for loose pipes by taking off the undercover rear part. Also check the boost solenoid is not blocked it can make a strange noise and can be found on the right side of the engine near the fuse box.

I would try to force regen it then clear the error and see if it returns and if so check the sensors. It might even be due to the others setting limp mode that the regen conditions are not set so fix the easy stuff first.
